Application filed April 30,1902. Serial No. 105,268. (No model.) I

To aZZ whom it may concern.-

Be it known that I, GEORGE W. MCGILL, a citizen of the United States, and a resident of Riverdale, in the county of NewYork and State of New York, have invented certain new and useful Improvements in Spring-Buttons, of which the following is a specification.

My invention relates to spring-buttons or fastening devicesfor gloves and such like purposes in which stud and socket members are employed to be inserted one within the other; and it consists in an improved mode of constructing the stud member of such devices, and specifically in an improved mode of constructing the spring stud member of the fastening device securedto me by United States Letters Patent N o.'-691,16 l, dated J anuary 14, 1902, in which such stud'lnember is made from a disk of sheet metal struck up to form an annular projection or'stud having a rentrant cavity central therewith and an outside encircling base-flange, the projecting annular stud beingradially slotted in manner to divideits annular-crown into a plurality of looped spring-sections having their opposite ends leading, respectively, from such outside encircling base-flange and the base of such reentrant central cavity.

In my improved device herein described the stud member consists of four pieces, as follows: a fingered spring part A, a holdingcollar B, a base-plate O, and an attachingeyelet or riveting-plate D.

In the accompanying drawings, in which similar reference letters and numerals indicate corresponding parts, Figure 1 shows a plan view of the metal blank of the spring part A, consisting of a series of spring-fingers 1, radiating from a common center 2, which center is provided with an opening 3. Fig. 2 is a side elevation of Fig. 1, having its center struck in a manner to cup its center and project its fingers 1 upward and outward ,producing a basket-like formation. The fingers forming the sides of this formation are further folded into loops, as shown in Fig. 3-that is to say, they are each folded outward and downward at point 4, then inward to a point, providing the heel 5, and again outward, providing the foot 6 and the open space 16 in the base part of each of such loops. Fig. 3 is a sectional side elevation of one-half otthe spring part so folded, showing the three farther or opposite looped springfingers thereof. Fig. 4 is a plan view of the holding-collar B, provided with an annular chamber or space 7, surrounding a central opening 8, and a dependent rim 9. lar is intended to bespru n g over the radiallydisposed looped spring-fingers of the spring.

This colpart A, as shown in the plan view Fig. 5 and in Fig. 6, which is a sectional side elevation of Fig. 5, taken on its line y y. Fig. 7 is a plan view, and Fig. 8 a cross-section, of the base-plate O of the device, provided on its upper surface with an annular ridge producing a chamber central therewith and an outer flange encircling such 1 ridge. Fig. 9 is a cross-sectional elevation of the completed device attached to a fabric 10. Fig-10 is a cross sectional side view of the attachingeyelet or riveting-plate Dof the device, and Fig. 11 is a side elevation of the completed device attached to a fabric, the latter, 10, being shown in section. Fig. 12 is a central transverse section of the base-plate (3, provided with a rim 16 at right angles with its body part. Fig. 13 is a view similar in Fig. 9, excepting that the collar B is shown therein without the dependent rim 9, and the base-plate O isshown provided with a rim 16, as shown in Fig. 12, and with a dependent tubular riveting-stem 18 integral with its open center and having its free end flanged upon the under surface of the riveting-plateD,

which latter is shown with a central aperture 19 and without a tubular stem. Figs. 14 and 15 are views similar to Fig. 13, excepting that instead of the base-plate 0 being provided with the tubular stem 18 it is provided with a central aperture 20, and a detached tubular stem 21 is shown binding the parts in Fig. 14:, whilea solid rivet 21 is shown performing the same office in Fig. 15.

In composing the device the fingered metal blank from-which the spring partA'of the device is fashioned is first struck in manner to cup its center 2 and project upward and outward its radiating spring-fingers .1, as shown in the drawings. These fingers,folded, looped, and radially disposed around the cupped center 2, as before described, are

sprung through the open center 8 of the collar B, their bulging spring-loops projecting over the outer surface of the top of such collar and their hooked feet occupying the annular space 7 in the under surface of same. The base-plate O is now inserted in the collar, with its annular ridge 11 projecting upward and occupying the open space 16 in the base of the loops of the spring part, the lower surface of such cupped center 2 occupying the chamber 12 of the base-plate G. The depressed rim 9 of the collar- 13 is now closed in upon the under surface of the periphery of the base-plate G, securing the latter in said collar, locking the feet 6 of the loops of the spring part in the annular space 7 of such collar, and securing the cupped center '2 of such spring part in the chamber. 12 of the base plate and permanently securing the parts in such positions with their respective openings 3, 8, and 13 coinciding, completing the device, which when thus completed is secured to a fabric 10 by passing the tubular stem 14 of the attaching-eyelet or rivetingplate D up through an opening of corresponding diameter made in such fabric and having its free end entered through the openings 3 8 13 in the stud proper and upsetting such free end in manner to flange it upon the floor of the cupped center 2 of the spring part A, as shown in section in Fig. 9, wherein the fabric 10 is represented as clamped and riveted between the folded rim of the collar B, under surface of the base-plate O, and upper surface of the flange 15 of the attaching-eyelet or riveting-plate D.

The dependent rim 9 may be omitted from the collar '13, as shown in Figs. 13, 14, and 15, and transferred as a vertical rim to the baseplate (J instead, as shown in those figures and in Fig. 12, so that the connection between the collar and the base-plate may be secured by crimping or fianging such vertical rim over the outer edge of the collar, as shown in Figs. 13, 14, and 15, and the center chamber 12 of said base-plate may be provided with a dependent tubularriveting-stem 18 to be passed down through the fabric, to which the stud member may be attached, and through a hole in the center of the plate D and riveted or flanged on the under surface thereof, as shown in Fig. 13, obviating its tubular stem as Well as the opening 3 in the cupped center of the spring part A, or instead of furnishing the base-plate C with such tubular riveting-stem and omitting the opening 3 a detached eyelet or rivet may be used in securing the stud to the fabric by upsetting the unflanged end of such eyelet or rivet on the floor of the cupped center of the spring part A, asin Fig. 14, where a tubular rivet or eyelet is shown, or on the under surface of said attachingplate D, as in Fig. 15,where a solid rivet is shown.

The spring stud member constructed as herein described will interlock with receiving socket members or eyelets of varying construction having the diameter of their receiving sockets or openings less than the diameter or spread of the bulb formed by the radially-disposed spring-loops forming the stud proper.
